I went from the SP-3's to the SP-4 speaker and MA-4 interconnect cables throughout my system. My interconnects are fitted with the Eichmann silver bullets and I opted for Mike's burn-in service which is highly recommended. The 4's have transformed my system into creating a very musical and natural performance I was not getting previously on my other "high-end" cables. For me, Morrow cables are the end of the search for the best cables at a reasonable price.
Question about Morrow ICs?
Are there significant differences between the various models MA1-MA6? Thanks!
